Thanks,

so that's a micro sim data sim right?

5 euros sounds good

keeps my son happy in the evenings

They sell both types of SIM.... in fact some of the locturios just sell a normal SIM and use a cutter to trim it down to a micro SIM.
For 5 euros you get a few minutes of talk time and a little data. Tell the locturio what you are going to use it for and he will out the best deal for a bolt on package. Mostly data or mostly voice or maybe a combo of both.

that's really helpful

thanks all
